Service Not Available but Billed Incorrectly

I requested by Contract for 30 G Data to be available on the 01st of September 2015 but when this date came and gone no Data was available. I contacted the Branch in Modimolle who is my contact and Debbie confirmed that the data requested can only be available by 13 September 2015 as my previous contract only expires 12 September 2015. The answer was that I should by 2.5 G bundles at R 445.00 until 13 Sept 2015 if I wanted data. This was not as I expected and then decided to use my 3G ****le to work from and bought data from Telkom as this was the cheapest option. I still received a VOX bill and stopped payment. A month later I was billed for R 51200.00 + the Bundle that I never received. I again stopped the payment and still they cannot get the message that they are in the wrong. Today Nonhlanhla from their accounts department phoned me for the 2nd time telling me to look at my usage report. What they have not done is to check that the usage report shows 90% of the little usage that was used was during the night when everybody is asleep.<br> Still no positive result and nobody who understand my frustration with Vox.
